OpenRoads Designer Connect Edition Tip: How to use Survey TIW files from SS4

March 1, 2018

When implementing OpenRoads Designer Connect Edition for processing of survey, you will want to use any TIW files you created in SS4.

When you add and configure these TIW files you may find that processing fails in various ways. In one example, a survey data file processes in SS4 and the list of point feature definitions seen in the Project Explorer is correctly shown with a variety of feature definitions:

Using the same TIW and same survey data in OpenRoads Designer shows the following:

This is caused by a change in the code of the software when reading the TIW file.

If you inspect the SS4 TIW file you will note an extra line in at the end of the file

To make the TIW work in OpenRoads Designer, simply remove the extra line.
